--- Comment #17 from Tobias Burnus <burnus at gcc dot gnu.org> --- (In reply to Tobias Burnus from comment #16) > ln -s include-fixed/$target $target/include-fixed That should have been: ln -s ../include-fixed/$target $target/include-fixed with that change, ./gcc/xgcc -v -B`pwd`/gcc foo.c works and shows: #include "..." search starts here: #include <...> search starts here: /tmp/tburnus-gcc-test/gcc/include /tmp/tburnus-gcc-test/gcc/powerpc64le-linux-gnu/include-fixed /tmp/tburnus-gcc-test/gcc/include-fixed /usr/local/include /usr/include/powerpc64le-linux-gnu /usr/include End of search list. ... # 30 "/usr/include/complex.h" 2 3 4 # 1 "/tmp/tburnus-gcc-test/gcc/powerpc64le-linux-gnu/include-fixed/bits/floatn.h" 1 3 4 and when continuing the bootstrap build, it now successfully finished with Stage 1 and I am positive that it will also finish building Stage 2 + 3.
